The seat belt buckle sensors (if
equipped) determine if the driver and
front passenger's seat belts are fas-
tened. These sensors provide the ability
to control the SRS deployment based on
whether or not the seat belts are fas-
tened, and how severe the impact is.(Continued)
• ABC – Always Buckle Children in
the back seat. It is the safest place
for children of any age to ride.
• Front and side impact air bags
can injure occupants improperly
positioned.
• Move your seat as far back as
practical from the front air bags,
while still maintaining control of
the vehicle.
• You and your passengers should
never sit or lean unnecessarily
close to the air bags. Improperly
positioned drivers and passen-
gers can be severely injured by
inflating air bags.
• Never lean against the door or
center console – always sit in an
upright position.
• No objects should be placed over
or near the air bag modules on
the steering wheel, instrument
panel, driver’s side knee bolster,
and the front passenger's panel
above the glove box, because any
such object could cause harm if
the vehicle is in a crash severe
enough to cause the air bags to
deploy.
(Continued)(Continued)
• Do not tamper with or disconnect
SRS wiring or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental deployment of the air bags
or by rendering the SRS inopera-
tive.
• If the SRS air bag warning light
“ ”remains illuminated while
the vehicle is being driven, have
an authorized HYUNDAI dealer
inspect the air bag system as
soon as possible.
• Air bags can only be used once –
have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
• The SRS is designed to deploy
the front air bags only when an
impact is sufficiently severe and
when the impact angle is less
than 30° from the forward longitu-
dinal axis of the vehicle.
Additionally, the air bags will only
deploy once. Seat belts must be
worn at all times.
(Continued)
WARNING
Always use seat belts and child
restraints – every trip, every time,
everyone! Air bags inflate with con-
siderable force and in the blink of
an eye. Seat belts help keep occu-
pants in proper position to obtain
maximum benefit from the air bag.
Even with air bags, improperly belt-
ed and unbelted occupants can be
severely injured when the air bag
inflates. Always follow the precau-
tions about seat belts, air bags and
occupant safety contained in this
manual.
To reduce the chance of serious or
fatal injuries and receive the maxi-
mum safety benefit from your
restraint system:
• Never place a child in any child or
booster seat in the front seat.

SRS Care
The SRS is virtually maintenance-free
and so there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate
when you turn the ignition ON, or if it con-
tinuously remains on, have your vehicle
immediately inspected by an authorized
HYUNDAI dealer.
Any work on the SRS system, such as
removing, installing, repairing, or any
work on the steering wheel, the front
passenger's panel, front seats and roof
rails must be performed by an authorized
HYUNDAI dealer. Improper handling of
the SRS system may result in serious
personal injury.WARNING
• Modification to SRS components
or wiring, including the addition
of any kind of badges to the pad
covers or modifications to the
body structure, can adversely
affect SRS performance and lead
to possible injury.
• For cleaning the air bag pad cov-
ers, use only a soft, dry cloth or
one which has been moistened
with plain water. Solvents or
cleaners could adversely affect
the air bag covers and proper
deployment of the system.
• No objects should be placed over
or near the air bag modules on
the steering wheel, instrument
panel, and the front passenger's
panel above the glove box,
because any such object could
cause harm if the vehicle is in a
crash severe enough to cause
the air bags to inflate.
• If the air bags inflate, they must
be replaced by an authorized
HYUNDAI dealer.
(Continued)
(Continued)
• Do not tamper with or disconnect
SRS wiring, or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental inflation of the air bags or
by rendering the SRS inopera-
tive.
• If components of the air bag sys-
tem must be discarded, or if the
vehicle must be scrapped, certain
safety precautions must be
observed. An authorized
HYUNDAI dealer knows these
precautions and can give you the
necessary information. Failure to
follow these precautions and pro-
cedures could increase the risk
of personal injury.
• If your car was flooded and has
soaked carpeting or water on the
flooring, you shouldn't try to start
the engine; have the car towed to
an authorized HYUNDAI dealer.

Additional safety precautions
• All occupants should sit upright, fully
back in their seats with their seat belts
on and their feet on the floor.
•Passengers should not move out of
or change seats while the vehicle is
moving.A passenger who is not wear-
ing a seat belt during a crash or emer-
gency stop can be thrown against the
inside of the vehicle, against other
occupants, or out of the vehicle.
•Each seat belt is designed to
restrain one occupant.If more than
one person uses the same seat belt,
they could be seriously injured or killed
in a collision.
•Do not use any accessories on seat
belts.Devices claiming to improve
occupant comfort or reposition the seat
belt can reduce the protection provided
by the seat belt and increase the
chance of serious injury in a crash.
•Passengers should not place hard
or sharp objects between them-
selves and the air bags.Carrying
hard or sharp objects on your lap or in
your mouth can result in injuries if an
air bag inflates.•Keep occupants away from the air
bag covers.All occupants should sit
upright, fully back in their seats with
their seat belts on and their feet on the
floor. If occupants are too close to the
air bag covers, they could be injured if
the air bags inflate.
•Do not attach or place objects on or
near the air bag covers.Any object
attached to or placed on the front or
side air bag covers could interfere with
the proper operation of the air bags.
•Do not modify the front seats.
Modification of the front seats could
interfere with the operation of the sup-
plemental restraint system sensing
components or side air bags.
•Do not place items under the front
seats.Placing items under the front
seats could interfere with the operation
of the supplemental restraint system
sensing components and wiring har-
nesses.
•Never hold an infant or child on your
lap.The infant or child could be seri-
ously injured or killed in the event of a
crash. All infants and children should
be properly restrained in appropriate
child safety seats or seat belts in the
rear seat.
Adding equipment to or modifying
your air bag-equipped vehicle
If you modify your vehicle by changing
your vehicle's frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle's air bag system.
WARNING
• Sitting improperly or out of posi-
tion can cause occupants to be
shifted too close to a deploying
air bag, strike the interior struc-
ture or be thrown from the vehicle
resulting in serious injury or
death.
• Always sit upright with the seat-
back in an upright position, cen-
tered on the seat cushion with
your seat belt on, legs comfort-
ably extended and your feet on
the floor.

Use high quality ethylene glycol
coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
Change to "winter weight" oil if
necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING- Tire chains
• The use of chains may adversely
affect vehicle handling.
• Do not exceed 30 km/h (20 mph)
or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
• Drive carefully and avoid bumps,
holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
• Avoid sharp turns or locked-
wheel braking.
CAUTION
• Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-
pension, body and wheels.
• Stop driving and retighten the
chains any time you hear them
hitting the vehicle.

FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.This vehicle has 4 fuse panels, one locat-
ed in the driver’s side panel bolster,
another is in the front passenger’s side
panel bolster, the others are in the
engine compartment.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check the
appropriate circuit fuse. If a fuse has
blown, the element inside the fuse will be
melted.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, discon-
nect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,
and fusible link for higher amperage rat-
ings.
✽NOTICE
The actual fuse/relay panel label may
differ from equipped items.
WARNING - Fuse replace-
ment
• Never replace a fuse with any-
thing but another fuse of the
same rating.
• A higher capacity fuse could
cause damage and possibly a
fire.
• Never install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and a possible fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove fuses
because it may cause a short circuit
and damage the system.

LIGHT BULBS
Use only the bulbs of the specified
wattage.
✽NOTICE
After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorized HYUNDAI dealer.

WARNING - Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the ignition switch is turned to
the LOCK position and turn off the
lights to avoid sudden movement
of the vehicle and burning your fin-
gers or receiving an electric shock.
CAUTION
Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause
damage to the fuse or electric
wiring system.
CAUTION
If you don’t have necessary tools,
the correct bulbs and the expertise,
consult an authorized HYUNDAI
dealer. In many cases, it is difficult
to replace vehicle light bulbs
because other parts of the vehicle
must be removed before you can
get to the bulb. This is especially
true if you have to remove the head-
light assembly to
get to the bulb(s).
Removing/installingthe headlight
assembly can result in damage to
the vehicle.
